<div>I has some experience with PETSc + MPI, but neither with PETSc+Pthreads nor Pthreads alone. Taking in to account that pthread was recenltly added to petsc, is it possible to code a program that solve the same linear system with two different solvers, one on each thread?. I guess that can be done calling different ksp object, one on each thread, but I don't have clear, first if this is possible and second how to do that. Sorry if my question is meaningless, I just started to study pthreads.</div>
